When every minute on the job site counts, the last thing you need is a screw that fights back. GRK R4 Framing and Decking Screws are engineered to work as hard as you do — driving faster, holding stronger, and outlasting the conditions your projects demand.

Say goodbye to the frustrating extra steps that slow down your workflow. These screws are built for professionals and serious DIYers who refuse to settle for ordinary:

• No predrilling needed — The fast bite tip digs in immediately, saving you time on every single fastener.
• Zero stripping frustration — Six points of stardrive contact mean you stay in control, every drive, every time.

• No split wood, no wasted material — The proprietary CEE Thread™ design gently enlarges the hole as it drives, protecting your boards from cracking.
• Flush, clean results — Cutting teeth slice through wood fiber so the head seats perfectly flush without tearing up your surface.

• Built for the elements — Climatek™ coating is AC257 code approved for use with treated lumber, so your connections stay strong even in harsh outdoor conditions.
• A tighter grip where it matters — An optimized thread length maximizes clamping force, pulling materials together with authority.

Versatile enough to tackle wood, sheet metal, cement fiber board, particle board, melamine, and plastic, these #10 x 31/2" screws are the one box you reach for across virtually every phase of a build. And with 1,200 screws per box, you've got the volume to power through big projects without running out at the worst moment.
